## Max. :6.825Di situ terdapat nilai min, quartil pertama, median,mean, quartil ketiga, max dan lain sebagainya. Tetapi, jika ingin melihat secara lebih spesifik, bisa menggunakan fungsi spesifik: 1. Rata-rata suatu variabel
mean(data$Terendah)## [1] 6.359008- Nilai tengah suatu variabel
median(data$Terendah)## [1] 6.35- Melihat standar deviasi suatu variabel
sd(data$Terendah)## [1] 0.2108161- Mencari skewness dan kurtosis install package moments terlebih dahulu jika tidak punya. Sebelumnya, mari kita lihat terlebih dahulu pengertian skewness dan kurtosis. Skewness merupakan ukuran ketidaksimetrisan dalam penyebaran data. Terutama pada distribusi nilai. Tanda skewness diwakili dengan nilai positif, negatif bahkan nol. Skewness yang bernilai positif berarti ekor distribusi berada di sebelah kanan nilai terbanyak. Sedangkan Keruncingan atau kurtosis adalah tingkat kepuncakan dari sebuah distribusi yang biasanya diambil secararelatif terhadap suatu distribusi normal. Rata-rata dan ukuran penyebaran dapat menggambarkan distribusi data tetapi tidak cukup untuk menggambarkan sifat distribusi
library(moments)
skewness(data$Terendah)## [1] 0.1140124kurtosis(data$Terendah)## [1] 2.28709D. Menggambar histogram data 1. Histogram data terakhir
hist(data$Terakhir)
mari kita mencoba mengubah histogram:
hist(data$Terakhir, xlab = "Terakhir of data", ylab = "Frequency", main = "Histogram of INDF", ylim = c(0,80), xlim = c(6.0,8.0))
2. Histogram data pembukuan
hist(data$Pembukaan)
3. Histogram data tertinggi
hist(data$Tertinggi)
4. Histogram data terendah
hist(data$Terendah)
